Hello can anyone please provide me with some insight about turbo charger design? Specifically referring to the compressor and turbine blades? My inquiry is more directly aimed at the number of blades. On different turbos they use different numbers of blades and I'm wondering if a higher number of blade offers any better performance over a identically configured turbo with a lower number of blades.
I have attached 3 images below. The first being a compressor side with a high number of blades, the second being a compressor side with a low number of blades, and the third being a turbine side with a high number of blades. It is important to note that the turbine side of a turbocharger is universally equipped with a high number of blades.
I would assume that a higher number of blades would provide a more uniform flow whereas a lower number of blades would provide more of a relatively pulsed flow. Also I would assume with all variables being equal between 2 turbos and only the number of blades being changed, that the turbo with the higher number of blades would provide more air flow.
I am no where near an expert and I hope someone with some knowledge will enlighten me. I thank you dearly for your time.
